Abstract
Description
- The present invention relates to internal combustion engines, and, more particularly, to a method and apparatus for filtering particulates from an exhaust stream in such an internal combustion engine.
- In order to meet future particulate emission standards for internal combustion (IC) engines, in particular diesel engines, manufacturers of diesel engines are using particulate filters (also referred to as particulate traps). Such particulate filters are typically placed downstream of the turbocharger turbine and remove solid particulate matter before it exits the exhaust system to the ambient environment. After a particulate filter collects particulates for a period of time, increasing the exhaust temperature to a suitable level cleans the filter (also known as regenerating) since the oxygen in the exhaust burns the accumulated carbon in the filter.
- Particulate filters for diesel engines are typically relatively large and expensive, and regeneration under light load conditions is problematic because attaining the necessary exhaust temperature is difficult. The use of particulate filters for diesel engines operating under varying load conditions therefore is quite limited. Even when the filter is regenerated, non-combustible ash which accumulates in the filter remains after regeneration, decreasing the efficiency of the filter.
- What is needed in the art is a diesel engine which uses a particulate filter to remove solid particulate matter from the exhaust emissions, which effectively removes both combustible and non-combustible particulates from the filter.
- The invention comprises, in one form thereof, an internal combustion engine including a first set of combustion cylinders, a second set of combustion cylinders, and a turbocharger having a turbine. A first particulate filter includes a bottom inlet in communication with the first set of combustion cylinders, a top outlet in communication with the turbine, and a generally vertically upward flow path through the first particulate filter inlet. A second particulate filter includes a bottom inlet in communication with the second set of combustion cylinders, a top outlet in communication with the turbine, and a generally vertically upward flow path through the second particulate filter inlet. An ash accumulation receptacle is positioned generally below each of the first particulate filter inlet and the second particulate filter inlet.
- The invention comprises, in another form thereof, an internal combustion engine including a plurality of combustion cylinders, and a turbocharger having a turbine. Each of one or more particulate filters includes a bottom inlet in communication with a set of the plurality of combustion cylinders, a top outlet in communication with the turbine, and a generally vertically upward flow path through the inlet. An ash accumulation receptacle is positioned generally below each inlet.
-
FIG. 1 is a schematic view of an embodiment of an internal combustion engine of the present invention; -
FIG. 2 is a side view of the dual particulate filter shown inFIG. 1 ; and -
FIG. 3 is a top view of the dual particulate filter shown inFIGS. 1 and 2 . - Referring now to the drawings, there is shown an embodiment of an
IC engine 10 of the present invention, which generally includes ablock 12 defining a plurality ofcombustion cylinders 14. In the embodiment shown,IC engine 10 is a diesel engine including sixcombustion cylinders 14, but may include a different number of combustion cylinders, such as eight, ten, twelve, etc. The plurality ofcombustion cylinders 14 includes a first set ofcombustion cylinders 16 which are in communication with anintake manifold 18 and anexhaust manifold 20; and a second set ofcombustion cylinders 22 in communication with anintake manifold 24 and anexhaust manifold 26. -
Exhaust manifolds turbocharger 28 including aturbine 30 which rotatably drives acompressor 32. The spent exhaustgas exits turbine 30 and is exhausted to the ambient environment, as indicated byarrow 34. -
Compressor 32 receives combustion air from the ambient environment, as indicated byline 36, and provides compressed combustion air tointake manifolds aftercooler 38 located downstream fromcompressor 32. - According to an aspect of the present invention, and referring to
FIGS. 1-3 conjunctively, adual particulate filter 40 includes afirst particulate filter 42 which is in fluid communication between first set ofcombustion cylinders 16 andturbine 30, and a secondparticulate filter 44 which is in fluid communication between second set ofcombustion cylinders 22 andturbine 30. Eachparticulate filter exhaust manifolds -
Particulate filter 42 includes abottom inlet 46 in communication withcombustion cylinders top outlet 48 in communication withturbine 30, and a generally vertically upward flow path throughinlet 46. Similarly,particulate filter 44 includes abottom inlet 50 in communication withcombustion cylinders top outlet 52 in communication withturbine 30, and a generally vertically upward flow path throughinlet 50. Eachinlet particulate filter outlet foot 53 allowing mounting to a turbine inlet ofturbocharger 28. - It will be appreciated that the flow path may deviate somewhat from vertical through each
particulate filter particulate filter IC engine 10 is turned off.Ash accumulation receptacle 54 is positioned at a bottom of eachparticulate filter inlets Ash accumulation receptacle 54 can be a fixed, non-removable receptacle as shown, or can be removable such as a removable tray.Ash accumulation receptacle 54 includes asloped floor 56 terminating at anoutlet 58.Outlet 58 is coupled with abypass 60, configured as a pipe in the embodiment shown, which in turn is coupled with a downstream side ofdual particulate filter 40. The higher pressure at the upstream side offilter inlets particulate filters IC engine 10. Anoptional valve 61, shown in dashed lines inFIG. 2 , allows controllable bypassing of ash throughbypass 60. For example,valve 61 could be opened at start-up ofIC engine 10 and closed during normal operation. - To further assist in removal of non-combustible ash from
particulate filters FIG. 3 ) vibratesparticulate filters IC engine 10 is turned off. Vibrator 62 is engaged or coupled withparticulate filters particulate filters - During operation of
IC engine 10,first particulate filter 42 filters particulates fromcombustion cylinders second particulate filter 44 also filters particulates fromcombustion cylinders ash accumulation receptacle 54.Optional vibrator 62 can be used to further assist in removal of ash fromdual particulate filter 40. When IC engine is again turned on, the accumulated ash bypasses arounddual particulate filter 40 throughbypass 60.First particulate filter 42 and/orsecond particulate filter 44 also can be regenerated (i.e., cleaned) using conventional regenerating techniques. - In the embodiment shown, each
particulate filter common turbocharger 28. However, it is also possible to couple eachparticulate filter turbocharger 28 is assumed to be configured as a variable geometry turbocharger (VGT), but may also be configured as a fixed geometry turbocharger. - Having described the preferred embodiment, it will become apparent that various modifications can be made without departing from the scope of the invention as defined in the accompanying claims.
